In large part, memory _is_ the only factor. Or, at least, a very large
one. Memory bandwidth, that is. Processors speed increases have
continued to outstrip that

There does seem to be a speed difference. I

There certainly is a potential speed advantage, but you won't see it
automatically just because you switch to a 64-bit processor (or to a
64-bit OS on a CPU t

Recent cpu-cores have greatly simplified pipleines compared to
pentium4,powerPC, etc.
the cores in core2d
Our experience is that x86_64 does have a speed advantage in 64bit
over 32bit -- this is for heavy compilation and running of computer algebra
